Here's a quick configure.ac and src/Makefile.am that produced
reasonable results for me.  Note that this does not address
things like LUA_USE_MKSTEMP for the following reason:
it would be possible to have the configure script define
LUA_USE_MKSTEMP on the commad line, but the norm would
be to define HAVE_MKSTEMP in config.h  (which ought to
either replace luaconf.h or be included by it) and
check for HAVE_MKSTEMP in the source.

If anyone feels like this would actually be worthwhile,
I'd be willing to spend some time working on it, but
I'm of the mind that it's really not...I suspect most
people copy the source files and compile them into
their projects rather than linking against an installed
liblua.  (At least, that's what I'm doing...but I've only
just started looking at Lua)
